DOVER, Del. - Joey Logano continued writing a wildly successful history at Dover International Speedway Saturday, winning his fourth consecutive Nationwide Series race at the fast 1-mile track, although his Ford failed post-race inspection.

Logano won the 5-Hour Energy 200 in a breeze, finishing 14.59 seconds in front of second-place Kyle Larson. Completing the top five were Kevin Harvick, Brian Vickers and Elliott Sadler.

After the victory lane celebration, NASCAR announced that the front end of Logano's Mustang measured too low on both sides in post-race inspection. Typically, such violations result in fines and/or point penalties, not in loss of the race win.

NASCAR said the car would be examined more closely at its Research and Development Center in Concord, N.C., early next week. Any penalties would follow.

Logano, a Sprint Cup regular driving for Penske Racing, became the first driver to win four consecutive races in any major NASCAR series at Dover.

"This is such a great racetrack," said Logano, who led 106 laps, including the final 59. "It's so much fun to run around it. You feel the speed throughout the whole race. It's such a physical racetrack. To sweep the last two years (two races per season) in the Nationwide series is really cool."

Logano, who started on the pole, said his car was loose in the early laps. "The team went for it with changes," he said. "These Nationwide races are short. You have to make big swings at it real early. We got it pretty close, and we had one more stop to fine-tune it."

Series point leader Sam Hornish Jr. ran into a pothole of sorts, absorbing a penalty for speeding on pit road near the race's halfway point and falling two laps off the lead pace.

Hornish, who led the points for six consecutive races entering Saturday's 200-miler, finished 17th. His points lead of 15 over second-place Austin Dillon - who finished sixth Saturday - fell to four. Sadler is third, 42 behind, with five races left on the schedule.

Kyle Busch led 89 laps but finished eighth after pit strategy put him behind Logano over the closing miles.

Oddly, the final 160 laps of the race's 200 were run without a caution flag; there were only two during the race, providing few opportunities for midrange cars to cut their deficits on the leaders. Only the top four drivers finished all 200 laps.

Larson said Logano's domination was produced by a combination of things.

"After my first Dover race, I thought this place sucked and that it is all about the car," Larson said. "But today I saw that the driver is a big key in it. You move around a lot throughout the race, and you're searching. Joey was really, really good all day."
